Useful Spacemacs commands

SPC q q - quit
SPC w / - split window vertically
SPC w - - split window horizontally
SPC 1 - switch to window 1
SPC 2 - switch to window 2
SPC w c - delete current window
SPC TAB - switch to previous buffer
SPC b b - switch buffers

When receiving JSON data from other resources(server API etc), we need Json.Decode to convert the JSON values into Elm values. This gist let you quickly learn how to do that.

I like to follow working example code so this is how the boilerplate will look like:

import Graphics.Element exposing (Element, show)
import Task exposing (Task, andThen)
import Json.Decode exposing (Decoder, int, string, object3, (:=))

Sonic Pi 2.2 at Bett 2015

This is a summary of a talk given at Bett 2015 on Sonic Pi

I started by playing excerpts from two programs, Scott Joplin Maple Leaf Rag, and a Percussion Generator, to illustrate different things Sonic Pi can do, and gave a brief description of Sonic Pi and the user interface, similar to section 1.2 of the built in tutorial, which is accessed by clicking the Help button.

I also showed how one of the example programs "Idm Breakout" could be copied and played. Then I used the following program sections to develop a code to play the round Frere Jaques
